They said they didn’t shoot Harrouff because they feared hitting Stevens.

McGraw ended the interview by promising to work with Harrouff’s father to learn why he snapped.

“You keep hanging in there and we are going to look for answers,” McGraw told him.

Harrouff’s family has said he had been acting strange for weeks before the attack.

His mother, Mina Harrouff, told police he claimed to have superpowers and that he had been sent to help people.

She said his bed had been moved to the garage because he thought there were demons in the house, and that a few hours before the attack, she stopped him from drinking cooking oil from the bottle, only to find him eating a bowl of cooking oil and cheese.
